DR Racer Help - Shawn? What are the differences here?

RRS claimed they sent “a”, but recd “b” instead (box says A, btw)

Seems there is a few ounce difference, but I’m wondered if someone could confirm this. Any significant difference other than weight?

thanks!

Same shoes, the laces are different colors. They changed them to red. Can’t comment on the weight, other than most companies are inaccurate when it comes to the correct weight vs listed weight.

Thanks!
